Description
Technical field
The present invention relates to a kind of Fish foster-mother, further relate to the nursing method of this foster-mother.
Background technology
During seawater fish hatching, how to improve incubation rate, how to improve the survival rate just incubating juvenile fish after hatching
Have become as a bottleneck problem of impact seawater fish seed breeding efficiency.At this stage, seawater fish incubating oosperm is main
There are three kinds of modes：Indoor cement pit is directly hatched, hatching barrel hatching and the outdoor big pool simple couveuse hatching.According to actual production
Data display, the average percentage hatch rate of these three hatching patterns in 70-80% about and incubation rate is unstable, wherein adopt outdoor big
The effect of the pool simple couveuse hatching is affected maximum by weather, and incubation rate is very unstable.As can be seen here, in order to improve sea water fingerling
The production efficiency of Seedling hatching, letter seawater fish to be improved hatchability of fertile eggs in seawater fish hatching process.
Seawater fish is in hatching process mainly through endogenouss vegetative phase, Combination vegetative phase and exogenous nutrition
Stage.Endogenouss vegetative phase nutrition main source is yolk sac and oily ball.In the external source nutrition intake stage, just incubate juvenile fish and incubating
If can not ingest rapidly after change, starvation can lead to high-volume dead.After hatching, due to incubating the device of ingesting of juvenile fish at the beginning of seawater fish
Official, organ of locomotion incomplete development, the ingestion ability of this stage juvenile fish is weak, is in and passively ingests the stage.Now due to itself because
Element limits so that just incubating ingesting of juvenile fish to become the primary factor of its survival of impact.In production, just incubate taking the photograph of juvenile fish to improve
Food success rate, it will usually feed using high density wheel animalcule, can improve the success rate of ingesting just incubating juvenile fish to a certain extent.So
And, production typically carries out nursery using big water body, due to constant number in water body for the juvenile fish, food ration is limited, using height
Wheel animalcule feeds density, can cause unnecessary waste, greatly increases production cost.Moreover, too high biological feed is close
Degree, can lead to seedling water water quality deterioration, also juvenile growth survival is had a negative impact.Therefore, how to improve and just incubate juvenile fish
Success rate of ingesting be to effectively improve the only way which must be passed of marine fish seed large-scale production efficiency.
During marine fish hatching, such as plectropomus leopardus, malaber reefcod, Epinephelus coioides etc., juvenile fish is external
Boundary stimulates irritability strong.Using traditional hatching method, can be related to just to be incubated juvenile fish and be transported to nursery pond, due to hatching barrel
The water quality environment of (pond) and nursery pond (bucket) and the difference of parameter, have certain stimulation to just incubating juvenile fish.In transport process,
Stimulate irritability due to just incubating juvenile fish body by force in extremely fragility of secondary stage and to external world, can cause death phenomenon.Therefore, how
Solve the problems, such as the strong seawater fish hatching of irritability and put Seedling be effectively improve necessity of seawater fish seed large-scale production because
Element.
Content of the invention
The technical problem to be solved is it is simply that run into fertilization for during seawater fish seed large-scale production
The technical problem that egg hatching rate is low, newly hatched larvae food ration finite sum survival rate is low, devises a kind of seawater fish foster-mother.
Solve above-mentioned technical problem, the technical solution used in the present invention is as follows：
A kind of seawater fish foster-mother, including be provided with the variable frequency pump of inlet regulating valve, housing, at least four be provided with water outlet
The outlet pipe of regulating valve, spiral water inlet pipe；Described foster-mother housing by upper end open cylindrical cavity part and stand upside down circle
Cone cavity portion forms, and is provided with the fixing buoyancy aid enclosing, described cone cavity in the junction outer wall of two cavity portion

Water inlet pipe, pump intake is connected with described four outlet pipes respectively；The other end of described four outlet pipes is each tightly connected circular cone
Outlet on face；
Flow of inlet water is controlled by described variable frequency pump, the water outlet of described spiral water inlet pipe shape in described foster-mother cavity
Become and be vertically vortexed；Adjust the flow of four outlets, formed in foster-mother cavity and be laterally vortexed.So in foster-mother cavity
Form vertically vortex to be vortexed with horizontal, wheel animalcule density can be improved in limited space, help and want newly hatched larvae motion, ingest,
And then improve newly hatched larvae survival rate.
Further, micropore gas explosion head, air pump and high-pressure air pipe are also included, described micropore is quick-fried to be provided with through hole in a fit of anger,
Described micropore gas explosion head is inserted in described cone cavity through the sealing of described through hole, and is nested in described by described through hole
On spiral water inlet pipe；Described micropore gas explosion head is connected with described air pump by described high-pressure air pipe, and input air keeps child care
In device, dissolved oxygen reaches saturation.
Further, the side wall of the cylindrical cavity part of described foster-mother housing is arranged with four water outlet windows,
Described water outlet window passes through to shine reel wire closing.Each outlet described and each water outlet window are equipped with solarization reel wire.
Further, also include a circular adjustable buoyancy aid, described adjustable buoyancy aid is fixed on described foster-mother
The inner side of housing upper end, for increasing buoyancy.
Preferably, the material of described foster-mother housing is PE material, and passes through injection mo(u)lding.
A kind of nursing method of the use present invention, comprises the steps：
1) place germ cell in foster-mother, adjust inlet regulating valve, go out water regulating valve, make water body exchange rate in foster-mother
Reach per hour 30%, hatch 4 days.
2), after hatching 4 days, water body exchange rate in foster-mother is improved to per hour 70%, and continues to hatch 7 days.
3), the 7th day after hatching, seedling is moved in seedling water from foster-mother.
The present invention compared with prior art, has the effect that：
1st, present configuration advantages of simple, forms vertically vortex and horizontal vortex in foster-mother cavity, and passes through micropore
Gas explosion head keeps the water body dissolved oxygen saturation in foster-mother, solves that current ocean fishes class hatchability of fertile eggs is low, newly hatched larvae is ingested
The low problem of amount finite sum survival rate.
2nd, the present invention passes through fixing buoyancy aid and adjustable buoyancy aid, foster-mother is suspended in nursery pond and is hatched and protect
Educate, after child care, Seedling is put in former pond, effectively reduce and put the secondary stimulus to prelarva during Seedling.
3rd, it is arranged with four water outlet windows on the side wall of the cylindrical cavity part of foster-mother housing of the present invention, and pass through
Shine reel wire closing, effectively keep the height of the water surface in foster-mother certain, prevent bait to run off because water overflows, Bu Huizao simultaneously
Become seedling water water quality deterioration.
